Abstract

The chlorofluoromethylene (CFCl) molecule has been generated from the infrared multiple-photon dissociation (IRMPD) of 1,2-dichloro- 1,2-difluoroethylene (CFCl=CFCl) with an apparaent nascent vibrational temperature above 300 K. The overall vibrational rate constant of CFCl for relaxation into v"=0 has been determined to be k_v=(6.8±0.7)x10^-14cm³molecule^-1s^-1. Decay rates of CFCl(X¹A₁,000) with the stratospheric gases present in significant concentrations, N₂, N₂O, NO, NO₂, and O₂, are also reported. Of these substrate gases, only NO and NO₂ were observed to have significant rates of reaction. The others were found to be relatively unreactive. The decay rate constants for reaction with NO and NO₂ were found to be k=(8.7±0.7)x10^-15 and (1.6±0.2)x10^-14cm³molecule^-1s^-1, respectively, obtained at room temperature and 100-torr total pressure.
